Abstract
A method for assessing a method of functioning of a fuel injector in response to the application of a control voltage to at least one actuator of the fuel injector, including the steps of applying the control voltage to the at least one actuator of the fuel injector for a no-torque-generating injection into an engine, determining a fuel content in an exhaust tract disposed at an engine, comparing the determined fuel content with a specified comparison value, and assessing the method of functioning of the fuel injector based on the comparison result. Furthermore, also described is an evaluation device for assessing a method of functioning of a fuel injector in response to the application of a control voltage.
